Let's be real here: most of us trawl Twitter to follow Kanye's craziness or feed on a match or to follow the House of Cards/Breaking Bad hashtag trail, or to mock the Late Late Show, for a deliciously trivial bit of displacement activity.
But there's also highly useful business Tweet feed out there to be mined.
In a year when Irish tweeting activity really exploded, there are many more new names to watch and follow, as well as some old favourites in our top 50. For instance ...

Will there be more about happenings at the Irish HQ? Worth following to find out.
O'Connell's new boss, Stephen McIntyre, is the man tasked with building up Twitter in Dublin, tweeting on its active expansion at @stephenpmc.
Limerick startup superstars the Collison brothers, Patrick @patrickc and John @collision, are both great to follow. They've got a $1.75bn-valued company, Stripe, that's disrupting PayPal and make interesting observations on everything from self-driving cars to the nature of dreams to Ryanair's ticket prices, as well as fielding customers' queries directly themselves.
PayPal Ireland boss Louise Phelan is at @louise_phelan, where she even handles the odd job pitch and service query. She's American Chamber president and one of the most senior women in Irish business, keeping an eye on the foreign investment landscape as well as eBay and PayPal trends and US and Irish affairs, so it's well worth tracking her tweet thoughts.
